[[Westernanimation/MonstersInc Henry J. Waternoose III]] feared that his family's company would soon go bankrupt, so he turned to Bill, and agreed to build a door between Bill's realm and the monster world in order to save it.

Think of like Disney's very own ''ComicBook/CrisisOnInfiniteEarths'' [[JustForFun/XMeetsY meets]] ''Film/AvengersEndgame'' and ''VideoGame/SuperSmashBrosUltimate'' not only many Disney, Pixar, Marvel, Lucasfilm, Muppet and 20th Century Studios Heroes and Heroines (especially with [[WesternAnimation/JakeAndTheNeverLandPirates Captain Jake]], of all people due to him being the most competent from all of the Disney Junior representatives who can be the analogue to Kirby (sans the Copying Powers thing, however) for Disney's very own Super Smash Bros. Ultimate) team-up to stop Bill Cipher, but with Disney inviting other GuestFighter Companies such as Warner Bros. (who wouldn't like to see [[ComicBook/JusticeLeague Superman, Batman, many of the Green Lanterns, Green Arrow, Flash, Wonder Woman, Booster Gold]] [[Franchise/MortalKombat Liu Kang, Kung Lao, Cassie Cage, Jax Briggs, Sonya Blade, Li Mei and Lord Raiden]] being among the people to stop Bill Cipher, complete with [[Franchise/StevenUniverse Stronger Than You]] being played), ViacomCBS (because it would be awesome to sse [[WesternAnimation/TheLoudHouse Lincoln and Clyde as Ace Savvy and One-Eyed Jack]] in addition to [[WesternAnimation/TheCasagrandes Ronnie Anne]] working together with many of the Heroic Residents of Gravity Falls to stop Bill Cipher), Universal (so we can see the ultimate CarFu moment featuring [[Film/TheFastAndTheFurious Dominic Toretto and Company]] in Weirdmageddon), SEGA (so we can have [[Franchise/SonicTheHedgehog Sonic and Sally]] with their friends joining forces to stop Bill Cipher), Bandai-Namco (so we can not only have a [[VideoGame/TalesSeries multitude of Heroes and Heroines of the Tales Multiverse teaming up altogether]], but to have [[VideoGame/{{Tekken}} Jin and the others (including Heihachi) in Weirdmageddon as well]]), Square-Enix with Taito (we would not only have [[Franchise/FinalFantasy Cloud, Tifa, Rikku, Vaan, Firion, Bartz, Tidus, Cecil, Terra, Lightning, Yuna, Zidane]], [[VideoGame/TombRaider Lara]], [[VideoGame/SleepingDogs2012 Wei]], [[VideoGame/ChronoTrigger Chrono with]] [[VideoGame/ChronoCross Serge]], VideoGame/SonicBlastMan and [[VideoGame/JustCause Rico]] but also to have the grand return of VideoGame/{{Gex}}), Ubisoft (who wouldn't like to see an AvengersAssemble scene featuring a [[ComicBook/SpiderVerse multitude of Spider-People]] and [[Franchise/AssassinsCreed Assassins]], led by Peter Benjamin Parker/Spider-Man and [[VideoGame/AssassinsCreedII Ezio Auditore da Firenze]], joining forces altogether to stop Bill Cipher?), Capcom (not only it would be awesome to see [[Franchise/StreetFighter Ryu, Ken and Chun-Li]] [[CoolVsAwesome pitting their]] [[UltimateShowdownOfUltimateDestiny biggest monstrous enemy to date since Galactus]], but also to have a reunion of ComicBook/{{Deadpool}}, ComicBook/{{Ghost Rider}} and [[VideoGame/DevilMayCry Dante]] (because Dante loves to fight against the evilest of Demons) and, [[Franchise/MegaMan not one, but five Mega Men, Proto Man, Axl, Bass, Zero and Roll]], [[VideoGame/{{Darkstalkers}} Morrigan]], [[VideoGame/ResidentEvil Chris, Jill, Leon and others]] like [[VideoGame/ViewtifulJoe Joe]] and [[VideoGame/GhostsNGoblins Sir Arthur]], to make it one of the two GrandFinale(s) for the Marvel vs. Capcom portion of the VideoGame/CapcomVs fighters), Kodansha (so we can see the ultimate MagicalGirlWarrior Team-up between [[Franchise/SailorMoon the Sailor Scouts]], [[WesternAnimation/StarVsTheForcesOfEvil Star with Marco]] (though Marco would have to be a BadassNormal) and [[VideoGame/PuyoPuyo Arle and Amitie]]) and more like [[Manga/MyHeroAcademia Deku with All Might]] and of all people who would be joining forces to end Weirdmageddon for good, [[Manga/OnePunchMan Saitama]] would have to be in it as well, as it would be the DreamMatchGame of a lifetime. What would be the thing to top it all off (except taken up to eleven times [[Franchise/DragonBall over 9,000]]) to make the MassiveMultiplayerCrossover version of the three-part GrandFinale even more Awesome? [[SugarWiki/AwesomeMusic Lifelight in Japanese]] sung by Erina Koga would be the theme song for [[ActionizedAdaptation Disney's Super Smash Bros.]] [[FanNickname Ultimate Weirdmageddon's]] Nintendo Switch version (for all regions).
